Each item is handcrafted with pride in villages on the Island of Bali using .925 sterling silver and ancient jewelry making techniques passed down through generations. Your purchase helps preserve the ancient traditions of this unique island by providing fair and sustainable income to Bali's independent artisans. As with all unplated .925 sterling silver, these pieces will develop a patina over time. Polish with a cotton fabric or a silver polishing cloth. These pieces should never be dipped in chemical cleaners because they can remove the oxidized accents which make Bali jewelry so attractive.2 5/8"
